The National Green Tribunal criticised Delhi Police and government agencies on Monday for not removing defunct vehicles parked on roads and asked them to strictly implement ban on vehicles which are more than 15-year-old.

A bench headed by NGT chairperson Justice Swatanter Kumar asked the municipal corporations to initiate joint action plan to ensure that all such vehicles are lifted so that no traffic congestion is caused.

"People have parked their vehicles on public roads.

Have you lifted a single vehicle which is parked on the road. We can't appreciate that none of the municipal corporations and DDA has lifted a single vehicle.

These vehicles are only standing on their rims, have no tyres or engines and being parked on public roads or at public places," the bench which also includes Justice U D Salvi said.

The green panel also directed the Delhi government, Delhi Development Authority, Delhi Police and municipal corporations to hold meeting and identify other sites which are to be provided in other places to ensure parking of impounded vehicles.

The directions came during the hearing of a petition filed by Vardhaman Kaushik over worsening air quality in Delhi.
